Antifibrotic effects of hepatic macrophages after MSCs treatment. Quantitative analyses of TGF-β1 (d), α-SMA (b), and COL1A2 (c) mRNA expression in hepatic stellate cells after 18 hours incubation with supernatants of hMø after in vitro treatments with DMEM (white bars), AdGFP-MSCs (gray) or AdIGF-I-MSCs (black) conditional medium. ANOVA Tukey's post-test, *p < 0.05; **p < 0.01, ***p < 0.001; * vs. DMEM hMø supernatants
